In order to use the Fettlebox 498 seal kit on an X246B, a "washer holder " is needed for the pump nrv. Where can one get them from (except from older pumps)?
Phil I have some of the original X246B pips as well as a couple of spare brass pip holders. I’d be happy to post a set to you. Otherwise, I bought the brass pipholders from Kibworth DIY through the bay of evil. Cheers Tony @phaedrus42
